American manufacturing has undergone a massive revolution over the past 20 years, becoming - gloomy perceptions to the contrary - the number-one manufacturing nation on earth. Cross the country with host Yul Kwon to look at traditional and not-so-traditional types of manufacturing. Along the way, meet the men and women who create the world's best and most iconic products, engineers who are reinventing the American auto industry, steelworkers who brave intense heat to accommodate radical new ideas about recycling and engineers who are re-imagining the microchip. Visit a small start-up company that is building personalized robots - machines that may one day reshape our homes and offices. Investigate the emerging notion that manufacturing itself is changing - from a system based on the movement and assembly of raw materials to a system in which ideas and information are the raw materials of a new economy.
